But measure it, and the particle snaps to one position. How do subatomic objects shed their quantum weirdness? Experts in the field of physics, including David Z. Albert, Sean Carroll, Sheldon Goldstein, Ruediger Schack, and moderator Brian Greene, discuss the history of quantum mechanics, current theories in the field, and possibilities for the future. This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation. Original Program date: May 29, 2014 Host: Brian Greene Participants: David Z. Albert, Sean Carroll, Sheldon Goldstein, Ruediger Schack Brian Greene&#039;s Introduction. 00:00 The double-slit experiment 4:03 Waves of probability. 10:50 Participant Introductions. 17:55 The classic outlook changed forever. 19:41 The Norman Ramsey approach to quantum mechanics. 22:44 The quantum measurement problem. 28:45 Does there need to be a clear separation between the quantum description and the observer? 31:44 How does the double slit fit into this example? 38:49 The many worlds approach to quantum mechanics. 45:48 If we can&#039;t see the other worlds, isn&#039;t that equal to believing in god or angels? 50:45 Summing up the many worlds theory. 59:52 Spontaneous collapse theory. 1:00:04 How do you make this theory precise. 1:08:00 Tallying the votes for collapse theory. 1:13:27 What is Qbism? 1:14:00 Does cubism gives a description of the world that needs an observer? 1:19:25 Two equations vs one. 1:27:04 The final vote for Qbism. 1:30:20 Don&#039;t miss a video! Subscribe NOW: https:\/\/www.youtube.com\/worldsciencefestival?sub_confirmation=1 ABOUT WORLD SCIENCE FESTIVAL: The World Science Festival (WSF) is a multimedia organization bringing the most transformative ideas in science to global audiences. Through long- and short-form videos spanning physics, cosmology, quantum mechanics, biology, neuroscience, consciousness, medicine, space exploration, the dilemma of free will, artificial intelligence, engineering, robotics, and beyond. WSF gathers world-renowned scientists, artists, and thinkers for dynamic discussions, debates, lectures, performances, films, and immersive live experiences. Founded in 2008 and headquartered in New York City, the World Science Festival is a production of the World Science Foundation, a 501(c)(3) nonprofit organization. Our mission is to cultivate a public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future. With live events reaching millions worldwide and hundreds of millions of digital views, WSF continues to expand its global impact through festivals, educational initiatives like World Science U, and digital content that explores the near and far future of our world.
